July 28, 1936. s. w. FORD HOLDER FOR CINEMATQGRAPH FILMS AND THE LIKE Filed Jilly 6, 1951 I N V EN TOR. GEORGE /V// hqM 5R0.

ATTORNEY Patented July 28, 1936 UNITED STATES HOLDER FOR CINEMATOGRAPH FILMS AND THE LIKE George William Ford, Kensington, London, England, assignor to Kinatome Patents Corporation, New York, N. Y., a corporation of New York Application July 6, 1931, Serial No. 549,067 In Great Britain December 16, 1924 24 Claims. (01. 88-17) This invention is for improvements in or relating to holders or cases, for cinematograph films and the like of the type which can be used as a container for the film to protect it during storage .5 or handling, and also serve as its carrier when in use in a projector or camera, the holder being so constructed that it is simply inserted into the clnematograph machine when it is desired to use the film. Such film-holders are constructed as fiat boxes in which are mounted two rollers or spools to which the film is permanently attached, and these rollers are so positioned, i. e. with their axes parallel, that the film can be transferred from one to the other without undergoing any twist. The rollers or spools are so formed as to engage with driving devices when the holder is inserted in position in a camera or projector.

According to the present invention a filmcarrying case of the type above described, that is to say, a case wherein the film is mounted on two rollers and which can be used for storage purposes or in a projector or in a camera, is constructed without any light passage through it. When the case is inserted in a projector, a section of the film is inserted in the gate for engagement by the usual feeding means and other mechanism of the projector in such a manner as to permit the beam of light for projection to pass through the film. When the case is placed in a camera, the film, without necessarily being displaced from the position it maintains while the case is used for storage, slips into the gate ready for operation without handling. Any suitable means may be used for protecting the exposed portion of the film or of the leader employed therewith, and according to another feature of the invention this protection may be afforded by means of an adjustable cover mounted on the case adjacent the exposed portion of the film, the cover being preferably so shaped as to provide a complete enclosure therefor when the film is not in use.

The present application is a continuation in part of my copending application Serial Number 72,855 filed December 2, 1925, maturing as Patent Number 1,944,023.

According to an important feature of the invention, that portion of the outside wall of the casing which is between the two openings in it and against which the exposed portion of the film lies,

is provided with a recess or is shaped re-entrantly so as to provide access to the rear side of the film. This arrangement facilitates the adjustment of the film when it is being inserted in a cinemator graph machine, permitting the easy insertion of the finger of the operator to draw out the film, or its engagement with a suitable guide on the projector or camera by means of which the film is conducted into the gate; the said recess may be closed on one of its sides by an extension of one of the flat walls of the complete casing.

Another feature of the present invention resides in the combination in a cinematograph projector, with a film-carrying case as above set forth. of a reflector which is situated within the loop of film exposed between the two openings of the case, whereby indirect lighting of the film is effected for the purpose of projection. With this arrangement, the source of light can be placed to one side of the film-carrying case and gate mechanism, and a length of film only sufiicient to provide accommodation for a small prismatic or other reflector need be drawn out from the casing.

Another important feature of the present invention resides in the construction of the recess in the film carrying case sufliciently large so that the reflector of the above mentioned projector, a gate member and a portion of the feeding means of the same may be accommodated within the recess so that no additional length of film whatever need be drawn out of the case, as will be readily apparent from the drawing.

In the accompanying drawing:

Figure 1 is a perspective view showing one construction of film-carrying case in accordance with the present invention;

Figure 2 is a side view, broken away in part showing the invention as applied to a camera with the film engaging mechanism of the apparatus disposed within the recess of the magazine.

Figure 3 is a schematic view looking at the structure of Figure 2 at right angles to the plane of the film path through the structure. Certain parts of the apparatus shown in Figure 2 are omitted from Figure 3 and a guiding and clamping finger of the invention is shown in this view which Referring first to Figure 1, the film-carrying case I0 is a fiat shallow container which is preferably made of thin metal. Its sides each consist of fiat plates having approximately semicircular ends H, I2. These two plates are connected together by a wall forming the edge, i. e. the sides and ends of the container, as indicated at l3. A roller or spool is rotatably mounted at the center of each of the semi-circular portions, and the spindles of these rollers may extend through openings [4 for connection with apparatus whereby they are driven, or whereby one of them is so driven.

On one of the sides of the container there are provided two openings I6, which may have any suitable light-traps such as are customarily used with films, and the film which is secured to each of the rollers aforesaid extends out of one of these openings and in at the other as indicated at IT. A sheet metal cover I8 is provided forthe casing and is adapted to cover that portion of the edge of the casing along which the film is exposed, so that when the cover is closed down the film is entirely enclosed and protected against risk of fire or other damage. Preferably the cover I8 is hinged to the case and is provided with any suitable detents or snap-fastenings l9 which will retain it in its closed position. A recess or notch I5 may be situated between the two openings l6 so that the film ll extends across it, such notch providing for the easy insertion of the finger of the operator to draw out a length of the film when desired, orfitting about one of the gate members and other parts of the cinematograph machine when such machine is so constructed that the film passes in a substantially straight line from one opening to the other. When this notch is used the cover I8 is preferably provided with a flange 20 which is of such a depth as to constitute a complete closure for the recess when the cover is closed.

Figures 2, 3, and 4 illustratemy magazine as cooperating with a camera or projector. As will be observed from these figures, the recess l5 accommodates a housing 22, semi-circular in cross section, within which the film moving member 23 may be positioned. One of the gate sections 24 is placed adjacent one edge of this housing, the member 23 working through an appropriate opening therein. The other and apertured gate section 25 is placed slightly forwardly of the section 24 or to the left as viewed in the drawing so that when the two portions are separated as the carrier is placed into position upon the spindles Nd and Hi the film itself without being drawn out from the case for any distance is positioned in the appropriate space between such gate sections. After the film has been inserted between the gate sections, said sections are maintained in operative relation with each other and the film therebetween in any conventional or wellknown manner. The usual shutter 28 may be provided mounted as upon the shaft 21 and operated by mechanism, such as a spring motor M having a shaft Ms, positioned within the casing 29, such mechanism likewise operating the moving member 23 and the take-up spindle [4t cooperating with the opening l4. Since these parts of the cinematograph machine form no part of the new structure of the invention, they are not described in detail. An appropriate housing 30 may be provided forwardly or to the left of the housing 22, as viewed in the figures. Upon such housing 30, the conventional objective lens 3i may be mounted. .A cover 32 hinged to the casing 29 at 33 as shown in Figure 2 may be provided whereby the film is protected from light when the camera is being operated. The engagement of the spindles in the holes I4 and the arrangement of the case ID for engagement with a mounting element 29' of the casing 29 serves to hold the case H1 in operative position on the apparatus.

Figure 4 illustrates my invention as applied to a projector. Referring to this figure, the source of light 38 may be arranged in a closed chamber situated adjacent the operating unit for the film. The light is passed through a suitable condenser 39 in the wall of the chamber and is reflected by suitable means, such as a prismatic reflector 40 situated immediately between the gate section 24, behind which and the gate plate 25 the film is passed. The projecting lens is indicated at 42.

In order to facilitate the insertion of the film into the gate, there may be provided guiding means, adjustable or otherwise.

If desired, such means may comprise a fixed guide member 34 over which the film is threaded, and according to another feature of the invention this guide member may be provided with adjustable finger or extension 35, hinged to the member 34, which can be swung upwardly to form a guiding surface cooperating with that of the member 34. This finger 35 can be inserted in the notch 15 behind the film, so that the act of placing the film-carrying case l0 into position automatically directs the film between the gate plates 24 and 25. When this position has been reached, the finger 35 is pushed down to retain the filmcarrying case 10' in its correct position. Any suitable spring control may be provided on this finger 35 to hold it in the two positions to which it is adjustable. Such guiding means may be applied to either camera or projector, and is illustrated in Figure 3 as applied to a camera and in Figure 4 as applied to a projector.

It will be readily understood, however, by those skilled in the art that in view of the fact that the film is not necessarily displaced from the straight line between the openings l6, this adjustable finger may be dispensed with. Oppositely curved extensions projecting upwardly from the gate sections 24 and 25 may be provided, if desired.

An important advantage of the film-carrying case constructed in accordance with this inven tion is that the over-all dimensions of the case can be reduced to a minimum, for the axes of the rollers can be arranged a shorter distance apart in the casing than in the film-carrying holders above described, since there is no need to provide space for the light passage through the I filmcase. Furthermore, it will be appreciated that the axes of the two rollers may be spaced apart a distance less than twice the distance of either roller from the adjacent semicircular end of the casing, since the full length of the film is either wound on one roller or distributed between the two rollers; if flanges are provided on these rollers, the flanges may overlap one another while still providing adequate accommodation for the film.

Further, it will be seen that this film-carrying case lends itself particularly to the use of indirect or reflected illumination of the film, which arrangement is advantageous in reducing the length of film which is exposed during its use.

A related and important advantage of this film-carrying case is that in the insertion of the film in the camera or projector or its removal therefrom, the film is not necessarily displaced from the position which it assumes while the case is being used for storage or transportation purposes and hence need not be handled by the operator or drawn out of the casing during threading. Thus the danger of fogging alight sensitive film or of injuring the first or last portion of a positive film, which portions are always subjected to maximum wear, is minimized. It will be readily understood that the protective casing 20 need not be removed from its protective relation to the film until just an instant before the camera is placed in operation.

It will be appreciated that the invention is not limited to the specific constructions hereinbefore described, and also that other details of construction of film-carrying cases such as are necessitated by the conditions of use and are commonly employed, may be used in connection with the present invention, and have not herein been described in detail.

Finally, it is to be understood that the expression cinematograph films and the like is intended to cover any films for use in a camera or projector, and whether used for motion pictures or still pictures, and cinematographic apparatus covers a machine used for theexposure or projection of pictures.
